Specification of Letters Patent. P t nt s 1914:.

Application filed January 3, 1914.; Serial No. 810,161.

' T o'all whom it may concern ments in Projectiles, of which the following i and showing with some parts broken away tip portion in longitudinal section. Fig. 3

f point-cap is a specification.

' This invention .relates to that class of projectiles which are usually made of elongated form and for use in small arms, and

especially to such projectiles having a soft metal core with an elongated point incased in a tip-casing or point-cap.

A principal object of my present improvements is to furnish an improved anchorage or interlocking construction as between the point-cap and the soft metal core, one particularly designed for use in elongated projectiles of the so-called mushrooming class. In the accompanying drawing, forming a (part of this specification," Figure 1 is a si e elevation of a projectile made in accordance with my present improvements, the projectile providedwith a main-core case, H, extending forwardly (toward the right hand) to a position about midway of the point-portion of the core, and with a point-capor jacket-tip, P, secured on the point of the core. Fig. 1 is a fragmentary view similar to the righthand portion of Fig. 1,for' showing a variation in the outline form of the. opening, 5, in the wall, t, of the point-cap P. Fig. 2 is 'a, viewv similar to Fig. 1, but shows the projectile as seen from below in Fig. l, and I to show the is a view similar to Fig. 2, but showing the P extending rearwardly outside of thereducedj forward end of the main core-casing, H, whereas in Figs. 1 and 2,

- there is shown a narrow zone of core-metal,

9, located between the separated edges, 2 and 3, of said core-incasing member's H and P, respectively. Fig. 3 illustrates a modification in the anchor device arrangement. Fig. 4 is an, enlarged sectional view,-of a diagrammatic character,-of a preferred form of the point-cap, but-with some portions omitted. Fig. 5 is an end elevation of that portion of the point which isfshown in Fig. 4c, as seen fromthe right-hand of said figure. Fig. 6 is a section on line Z Z,"Fig.f4,s'howing the parts at the right-hand of said line as seen from a point at the left-hand thereof.

Similar characters represent in all of the views.

In projectiles having incased soft-metal cores and formed with "elongated points, and owing partly tothe usual increase of the tangent-angle (of the curve of the point-cap surface) toward the apex-of the like parts nose or point, a point-cap or tip-casing made of the thin'metal sometimes used therefor, is not held in place with sufficient security by core-projections or plugs which simply extend outwardly into correspond mg perforations 'in su'ch a point-cap. This objection is especially important. when such openings arelocated relatively near to the extreme tip-end or apex of the projectile point. The limited coaction of such openings and projections is diagrammatically illustrated in Fig. t, in which 8 is, the longitudinal axis of the projectile, the point- P being shown section and having therein the opening 5 located'in a'po'sit'ion where the cap-wall tfis sharply inclined'to said axis line 8. I A. line 10 is drawn parallel to the axis 8 forshowing how ve'ry'small an amount of core metal,as indicated by the small shaded area at cZ,- operates'as a dete it or loclr forward of the narrow capwall edge e, for holding the cap P upon the core point 'C; and it will be evident that when the core is of lead or' of soft alloy, such holding power will be too slight for effective use with point-caps made with a very thin wall. For overcoming these liinitations and objections, I have devised the anchoragemeans which will now beflmore fully explained. p I 1 At the forward edge'of an opening, as 5, inthe' cap-wall t, provide an inwardly extending anchor, as N, which, in the preferred form thereof herein shown, is in the nature of a wall orvblade and is so located and shaped astoi beiadapted for being made by the turning inwardly of the metal, or a-portion thereof, which is removed for forming the said opening. This constructiomas will be evident, has the advantage of utilizing wholly, or in-part, themetal which would otherwise be removed, and of providing such an anchorage device or blade which shall be integrally connected for a. considerable dis;

tanc'e one side (iisually'the forward I wall, t, and

, gularfornrwhich it has relatively toa'geoe" sidell of the. opening with the wall of the point-case; this integral juncture of said at 6, Fig. 4. A further feature of the an 1 chor t device, when thus arranged andi'lo cated, is the transverse curvature or the an metric plane transversely of the axial, line 8,

as will appear obviousfrom a comparison ofethe severaljviews,particularly the diagramxFigsl 4, 5"'ancl6;. This transverse forv mation ofthe said anchorage'blade Nis a p "the principal views,"

In Fig. l this N, especially when it is set in an inclined poespecially opening is of non-curved outline, and 'the angular and braced formation of the metal along that line operates to stiffen both the wall, t, and the anchorage member 'Nyand to stiffen the'anchorage member as against the pressure oft-the flowing core: metal when the projectile is subjected to the j usual operation 'ofswaging 1 in a die for bringing t to finalsl1ape.,f Dur1ngthlsop eration the position of the anchorage blade sition, asindicated by the line 7", tends todi- I rect or deflect a portion of I metal, outwardly,
